RE: [DML] A/C conversion

["Marc A. Levy" <malevy@xxxx>]

This comes up every spring.

Some have had good luck with conversions, BUT I suggest sticking with R-12.

To do a proper R-134A conversion, every seal in the system needs to be changed, the receiver/dryer needs to be changed, and everything else needs to be properly flushed out. This is not a easy job to do CORRECTLY, and when your done you are still be stressing the components by putting them under 70% more pressure than they were designed for. The added pressure is also hard on the compressor, so you may be looking at replacing that too.

R-12 is not all that expensive, it is just hard to get without a license. There are good substitutes that have been discussed in the past, but I do not use them. I stick with pure R-12, no blends. Blended R-12 sometimes contains propane which is a excellent refrigerant, but VERY DANGEROUS!

You will also stay much cooler with R-12, without overworking the compressor (and taking more power from your wheels!)

Subject: [DML] A/C conversion


last summer my A/C system wasn't functioning so i took it in to my local shop 
to have them inspect everything for leaks. turns out pretty much everything 
is leaking on it. if i were to buy all new A/C parts, it would cost me a 
small fortune. how easy is it to substitute the entire system with modern 
R-134a components? how much will that cost and how easy is it to make 
everything work?
